B y referenceto Figs. 4, and 6, it will be seen that the knife'holder 30 is a boxlike structure swiveled on base plate a, which is secured by screws 32, on supporting block 33, whichis transversely slidable in a dovetail recess 34 in the uprightS (or 9, as the case may be). The dovetail slide 33 extends in a direction parallel with the edge ofthe knife v 31, so vthat successive sharper portions of the edge may be adjusted into engagement with the wire e0, when theiportions in use havebecome dull. The transverse.adjustment is controlled by screw 35 engaging screwlug 36 on the slide The screw 35 is prevented from endwise movement by swivel collar 37 and is operated by handle 3 8. The knife 31 is clamped in a tool holder 39 .by .Screw 40. The tool holderjis rotatably held n box 30 by flangeheaded screws 41, 41. The adjustment of the` knife is gauged by a. tail set screw 42 `against which it is held in firm engagement by spring 43 encircling screw 44 which .serves as means fol1 anchoring said spring. The other end of the spring engages a stud 45 on the knife blade 3l.

The entire tool holdingbox 30 pivots on screw 46, which is rigidly sc rewed into base 30a. When the direction of draft of the wire is reversed, the knife is reversed by pivoting about said screw 46. In either positionit is held by bolt 48, spring pressed downward byspring 49 and having a head 5G by which it may be retracted. 4 V and 6 the locking bolt hole not in use is marked 48a#- yIn actual practice, the sire 01" the teol holder, the position. of its pvot and thesiz'es Yofthe .rollers 20, 20, .are such that Vone position the knife edge will rest on ferie .roll at the Lend. .of its horizontal dt In Figs.

Fig. 9. The engagnlellt or release of .the spline-,may be effected by hand or in any other desired way. As shown in Fig. 8, the shaft 81,has a spline groove 82, in which is lengaged spline 83 Carried by an operating shank 84, by. which it may be retracted and turned to the position shown in Fig. 9. Preferably, there lisa detent v85, which fits a locking'recess V,8 6 when the spline is in groove ,82, .which is turned crosswse Vof said recess when said spline is retracted to hold itinthe retracted position, as indicated in Fig. 9.

As indicated by thearrows in Fig. 3, shafts 61 and 81 are rotated in the samedikrections by means of gears 61a, 8l, .engaging gear 90 0n the main drive shaft 91. lVhen it is desired to 4stop or reverse the direction of rotation of the reels, the shaft `91 will be stopped or reversed. Consequently, when reel 8.0 is splined to shaft 81, as shown in the drawings, the direction of rotation is such that the reel is being power rotated to wind up the wire. At this time the supply reel-,60 is free to rotate, opposed only by friction. Vhen reel 80 is unsplined and is splined, ythe direction of rotation is reversed so that reel 60 becomes the power drawing reel and 8O the supply reel.

As the end tension on the wire is always great, it is necessary to provide level winding means whereby the reels are reciprocated axially to lay the wire in smooth layers and to keep the winding point exactly the plane of the grooves in the peripheries of wheels 20. AIn the arrangement shown, .the reels are Ysimultaneously reciprocated through flange collars 62, which are rigid with the respective reels. Behind these collars are engaged lugs 63, carried byarms 64 projecting endw-ise from a sleeve 65 havinga cani slot 66 engaged by stationary camming pin 67 `SQCured to the frame by suitablev support 6 8, so that rotation of the cam sleeve necessarily Cams it endwse of the shaft. The cam slots 66 of the respective cam sleeves are arranged in like .phase and are `rotated by gears 68 slidably .engaging alongV pinions 69 on shafts 92 both Adriven by gear y9401i shaft 91. It will be understood that the gear train 94, .93, 69, 68, a reducing-gear train of such ratio that 'the reels 60and80 will be rotated enough times to lay `down and level wind a complete layer of wire Vduring the time that the sleeve 65 is being rotated a halt revolution. Such half revolution will cause the cam slot 66 to complete a one direction camming of the sleeve and attached drum in one direction, while a continuation of the slot will similarly complete a traverse in the other direction during the neXt half revolution.

From the above the operation of the device will be evident. One of the reels, as 60, is provided with a coil ot wire of any de sired length. The wire is threaded into the machine, in the grooves in the support rolls and under knives, 31 and over the large pulley 1G at the top; thence down in the grooves o'l the second set of rolls 20 under its set of knives 31; thence by guide pulley 201 to the reel SO, to which it is secured in any desired way. The reel 80 is then splined to its shaft S1 and the supply reel G0 is unsplined on its shaft. The drive shaft 91 being then started, the machine will operate until, when the wire on the supply reel is nearly run out, shaft 91 will be stopped, the spline engagements will be reversed, the locking bolts 48 will be retracted, the knife holders will be rotated upon pivots 46, through an angle ot 180 degrees to bring the edge of thel cutting knife into registry with the periphery of the .ne-Xt adjacent support roll 20, and, finally the shaft 91 will be re-started in the reverse direction, thus making reel the drawing reel.

The steel wool shaved by the knives 31 may be removed in any desired way, preferably by means of air jets directed through nozzles 100, 100, supplied with compressed air through pipes 101, 102, 103, 1041, 105, supplied by a centrifugal blower 106 of any desired type, rotated from an. suitable source of power as by belt 107. The wool driven ott by the air blast may be collected, as by a hood 108, leading to chute 109, shown in dotted lines in Fig. 1.

lt will be understood that the knives will be renewed and adjusted from time to time as may become necessary.
